Little numbers in this intro jump to the answer at the bottom, so you can settle each question without opening a new tab.
You were in bed by 10:40. Reasonable. Proud of yourself, even. Then, while setting the alarm, you glanced at one headline about how Roman concrete lasts two thousand years, and it's 1:51 now and you know about the seawater. It makes the concrete stronger.1 It's fascinating. You have to be up at 6:45.
And this is the good stuff, nowhere near a doomscroll. The mantis shrimp with twelve kinds of color receptors.2 Whether lobsters age.3 The entire history of the semicolon, one night in March, start to finish.4
Then the alarm goes off, and it stings twice. The 6:45 lands on less than five hours of sleep, the morning runs a step behind, and by the afternoon the whole day has paid for the random concrete fact that kept you awake for three extra hours. Meanwhile the drive itself, that lit-up, wide-awake, could-learn-anything drive, was nowhere to be found at 2pm when the boring task needed it. Where was this at 2pm. That question has an answer.
The first hour that's actually yours
Look at when it happens. It's at night, after the last obligation has gone to bed, in the first hour of the day with nobody's name on it.
This brain runs its attention on interest, and interest doesn't wear a watch. All day long, your attention gets fed scraps: the inbox, the forms, the errands, a hundred things chosen by the calendar instead of by you. Then the day finally goes quiet, and for the first time since you woke up, your attention is allowed to want something. Of course it eats. It's been hungry since morning.
There's wiring under it too. In adults with ADHD who struggle to fall asleep at night, the internal clock itself runs measurably late, with melatonin, the hormone that tells your body it's bedtime, arriving later than it does for people without ADHD.
